JEFFERSON CITY, Mo. — A Columbia, Missouri, man pleaded guilty in federal court today to his role in a conspiracy to distribute marijuana.

24-year-old Blake Jeffrey Johnson pleaded guilty to one count of conspiracy to distribute 1,000 kilograms or more of marijuana and one count of conspiracy to commit money laundering.

Johnson received high-grade marijuana from Augustus Roberts and received thousands of dollars per month from Roberts to distribute marijuana to co-conspirators.

Roberts was murdered at his residence on Dec. 10, 2017. At the time of Roberts’ murder, a U-Haul truck rented by Johnson had been parked in the driveway of Roberts’ residence, but was stolen during the home invasion. The U-Haul truck contained approximately 800 pounds of marijuana belonging to Roberts and his drug enterprise prior to the theft.

Columbia police officers found the truck the following day. Officers seized 6 boxes that contained a total of 94 gallon-sized bags of marijuana, five boxes that contained a total of 3,199 THC vaporizer cartridges, and three electric currency bill counters.

Roberts also distributed thousands of pounds of marijuana to other co-conspirators for between $800 and $2,500 per pound.

Johnson is the fifth defendant to plead guilty in this case.
